Te (7,217 whom z' c azy concem:

Be it known that I, JOHN W; VVHITE, a citizen of the United States, residing at 122 Bedford Avenu Buffalo, in the County of Erie and State of New York, have invented certain new and useful Improvements in Disk `Wheels, of which the following, taken in connection with the accompanying drawings, is a speciication.

This invention relates to an improvement in disk wheels and more particularly in. the means for assembling the wheel and for assuring the unitary movement of* the various elements.

One object of this invention is to provide a single nut forsecuring the disk upon the inner hub in contradistinction to the 'plurality of nuts or bolts previously used for this purpose.

A further object of the invention is the' provision of a plurality of corrugations in the inner hub with which corrugations a similarly corrugated periphery of the disk engages.

Other objects will appear from a consider- :tion of the following description taken in connection with the drawing which forms a part herof and in which- Fig. 1 is a cross section of the hub portion of a disk wheel embodying this invention;

Fig. 2 is a section taken along the line 2-2 of Fig. 1;

Fig. 3 is a View similar to Fig. 1 of another enbodiment of'this invention;

Fig. 4 is a cross section taken along the line 4-4 of Fig. 3.

Referring to the drawings, the reference number 10 is used to designate the inner hub of the wheel on which is mounted a disk 11, held in place by means of a shell 12 which in turn is Secured by means of the nut 13 threaded upon the outer end of the inner hub. The central portion of the inner hub 10 is made hollow in the usual manner to receive the vehicle aXle which carries the wheel and which is not shown in the drawing because it forms no part of this invention.

The inner hub 10 has a radial flange 15, at the periphery of which is formed a flange 16 at right angles to the flange 15 and parallel to the main portion of the inner hub. The under face of the flange 16 is provided with a series of equally s aced depressions 17, as shown for examp e in the flange 16 of the hub and is corrugated similarly thereto so that when the parts are assembled as shown in the drawings the expressions 19 of the disk flange 18 will enter the depressions 17 of the iange 16 thus preventing any relative rotation between the parts.

- The shell 12 is fianged at 20 to bear against disk 11 and flanged at 21 to receive the inner face of the nut 13, thus by tightening the nut 13 'the shell is forced against the disk 11 and holds it firmly in contact with* the rounded portion of the flange 16.` If desired the shell 12 may be permanently fixed to the disk 11 and since these -parts have a united action they may be referred to as the disk elements.

Since the edge of the flange 16 is rounded the disk 11 will be permitted to oscillate laterally without interference with the mounting. Thus any rigidly'clamping of the disk to the inner hub and consequent fatigue of the met-al at that point will be liminated and' the disk be free to weave without constriction throughout its entire surface.

' The flange 18 of the disk lies under the flange 16 of the hub so that the letter and consequently the entire weight of the vehicle is supported from the upper part of the wheels thus placing this wheel in the class of suspension or tension wheels The `form shown in Figur-es 3 and- 4 difl'ers fromthat shown in Figures 1 and 2 merely in the manner in which thedriving connection is provided between the disk and the inner hub. consequently the reference characters used in Figur-es 1 and 2 will be used in Figures 3 and 4 wherever pos-- sible and only the difierences between these embodiments will be described in detail.

The flange 15 of the innerhub 10 is provided with an annular flange 22'* against which rests the inner periphery 23 of the,

disk 11. At the joinder of the flanges 22 and 15 there is on the flange 15 a shoulder 24 against which the inner edge of the disk rests. The upper face of the flange 22 is provided with a series of depressions 25 and the periphery 23 of disk 11 is .provided with a similarl spaced series of expressions 26 so that w en assembled, the parts will assume the position shown in'Fi ure 4.

The shell 12 of the wheel earsagainst the outer face of the disk 11 andforces it into close contact with the shoulder 24. However, due to the fact that the, disk is not held between the shell 12 and any rigid member as in Figur-e 1, the disk will be absolutely free to weave. Since the inner`hub rests upon the disk flange the wheel may be said to be of the compression type the weight being supported by the lowest portion of the disk.

Obviously therefore, this second embodimentis in certain respects more flexible than in the first embodiment. Due however to the provision of the shoulder 24, the disk is held firmly in position upon the flange 22 and by reason of the depressions 25 and expressions 26 is caused' to move as a unit with the inner hub.

While two embodiments have been shown and described, I am not to be limited thereby since it is obvious that other embodi ments may be made without departing from the spirit and scope of my invention as set forth in the following claims. i

Having thus set forth my invention what I claim as new and for which I desire the protection of Letters Patent is- 1. In a disk wheel the combination of a `flange projecting one face of said annular flange being proclaim 1 the annular flange t hub, a, radial flan e thereon, an annular om said 'radial flange,

vided with corrufgations, a disk having an inner peri heral an e corrugated Conversely to sai annular ange -such corrugated surfaces bein in mesh when the wheel is assembled and 'means for holding said disk and hub assembled.

2. In a disk wheel of the type set forth in claim '1, the holding means there recited being carried b said hub.

3. In a dis wheel of thetype set for-th in claim 1 the holding means there recited comprising a shell bearin upon said disk and a nut carried by said ub looking said shell against said disk.

4. In a disk wheel ofthe t pe set forth in here recited being corrugated u on its under face.

5. In a disk w eel, an inner hub having a radial flange and an annular flan e at the periphery .of said radial flange, a isk having a central opening and a corru ated flange surrounding said opening, and aring upon said inner hub, corrugations on said inner hub meshin with said disk corrugations when the w eel is assembled; a shell clampin said disk against said annular flange-an a -nut carried by said inner hub for holding said shell in position.

In testimony whereof I afiix my signature.

JOHN W. WHITE.
